Yellow Card Scheme

What is it?
The Yellow Card Scheme is run by the MHRA and CHM. It collects, collates and investigates reports of suspected adverse drug reactions.  The scheme was set up in response to the thalidomide tragedy, which highlighted the urgent need for routine monitoring of the safety of medicines by a central body independent of the pharmaceutical industry.  It was the world’s first spontaneous reporting scheme for the reporting of suspected adverse drug reactions and is the cornerstone of post marketing drug safety surveillance in the UK. The scheme is voluntary and relies on the identification and reporting of adverse drug reactions by health professionals and patients.
